Definitions
- the present invention relates generally to whirlpools and spas, and, more particularly, to a method and apparatus for purging standing water from the water lines, fixtures, and jet manifolds during draining of the whirlpool or spa vessel.
- a whirlpool bath or spa typically includes a tub in which the water is circulated around the bather to provide a relaxing and therapeutic environment.
- Whirlpool baths generally accomplish this through the use of a hydraulic pump to circulate water from the interior of the bathtub through plumbing located on the exterior of the bathtub and back into the tub through a plurality of nozzles.
- Whirlpool baths can be commonly found in homes, health clubs, hospitals, and rehabilitation centers.
- whirlpool baths One concern currently receiving some attention regarding the safety of whirlpool baths relates to sanitation. Specifically, there is a concern that it is difficult to completely drain all of the water from the whirlpool circulation plumbing, resulting in an environment conducive to the growth of bacteria and fungi. Since the plumbing is principally located outside of the bathtub (and is usually covered), the plumbing is generally inaccessible without undertaking the major effort of disassembling and removing the tub itself. The inaccessibility of the plumbing makes it nearly impossible to prevent standing water from being left therein after each use of the whirlpool bath. This is a problem because the standing water typically includes residual soap scum, scale deposits, sloughed off skin cells, body oils and other fluids, fecal matter, and other bathing residue. The plumbing therefore provides a dark, warm, and moist environment in which bacteria and fungi may thrive.
- S. aureus is an etiological agent for bacteremia, endocarditis, pneumonia, empyema, osteomyletis, and septic arthritis and also releases a toxin responsible for scalded skin syndrome, toxic shock syndrome, and food poisoning. Id.
- the present invention relates to a method and apparatus for removing standing water from the plumbing in a whirlpool bath.
- One form of the present invention is a pneumatic pump fluidically coupled to the pipes and nozzles of the hydraulic piping of a whirlpool bath and adapted to flush standing water out of the hydraulic plumbing after each use of the bath.
- the pneumatic plumbing is positioned substantially above the maximum water level allowed in the tub and substantially above the hydraulic plumbing and is connected in fluidic communication with different portions of the hydraulic plumbing, such that activation of the pneumatic pump after the tub has been substantially drained forces residual water from the hydraulic plumbing.
- One object of the present invention is to provide an improved whirlpool bath system. Related objects and advantages of the present invention will be apparent from the following description.
- FIG. 1 is a perspective view of a whirlpool bathtub fitted with a residual water purging system of the present invention.
- FIG. 2 is an enlarged partial perspective view of a portion of the residual water purging system of FIG. 1.
- FIG. 3 is a schematic view of the residual water purging system of the present invention.
- FIGs. 1 and 2 illustrate one embodiment of the present invention, a system 10 for purging residual water from the whirlpool plumbing of a whirlpool bathtub.
- the water purging system 10 is adapted to use air pressure to blow residual or standing water from the water circulation plumbing used to generate the "whirlpool" effect in a whirlpool bathtub 20.
- the whirlpool bathtub 20 typically includes a water inlet 22 and a water outlet or drain 24 connected to a central plumbing system.
- the whirlpool bathtub 20 preferably includes an auxiliary water outlet/drain 26 positioned substantially above the water drain 24.
- auxiliary drain 26 functions to prevent an overflow of the bathtub 20, and effectively defines a maximum water level.
- the bathtub 20 may alternately include a single water drain 24 without an auxiliary drain 26.
- a typical whirlpool bathtub 20 also includes a water pump 30 having a water pump inlet 32 and a water pump outlet 34.
- the water pump outlet 34 is connected in hydraulic communication with a whirlpool hydraulic system of plumbing 36 and is adapted to pump water therethrough when actuated while the bathtub 20 is filled with water.
- the whirlpool hydraulic system 36 typically includes at least one suction fitting 38 formed through the bathtub 20.
- a suction conduit 40 extends from the suction fitting 38 to the water pump inlet 32, connecting the suction fitting 38 (and therethrough the bathtub 20) in hydraulic communication to the water pump 30.
- a plurality of water inlet or water jet nozzles 44 are also typically formed in the bathtub 20.
- a water manifold 46 is typically positioned around the bathtub 20 and is preferably positioned above the water level defined by the auxiliary drain 26.
- the water manifold 46 is connected in hydraulic communication to the plurality of water jet nozzles 44 by a plurality of water delivery conduits 48, each adapted to convey water from the water manifold 46 through the respective water jets 44 and into the bathtub 20.
- the water manifold 46 is also connected to the water pump outlet 34 by a water manifold conduit 49 extending therebetween in hydraulic communication.
- the water pump 30 When actuated, the water pump 30 is adapted to receive water from the bathtub 20 through the suction fitting 38 and suction conduit 40 and return water under pressure into the bathtub 20 through the jet nozzles 44 by way of the water manifold 46.
- the water purging system 10 of the present invention includes an air pump 50 having an air pump inlet 51 and an air pump outlet 52.
- the air pump outlet 52 is connected in pneumatic communication to an air manifold 54 through an air delivery conduit 56 extending therebetween.
- the air manifold 54 preferably extends around the bathtub 20 and is more preferably positioned above the water manifold 46.
- a plurality of air nozzle conduits 58 extend from the air manifold 54 to each respective water jet nozzle 44, connecting the air manifold 54 thereto in pneumatic communication.
- an air suction fitting conduit 60 extends from the air manifold 54 to the suction fitting 38, connecting the air manifold 54 in pneumatic communication to the suction fitting 38.
- an air suction conduit conduit 62, and air water manifold conduit 64 and an air water pump outlet conduit 66 extend between the air manifold 54 and the suction conduit 40, the water manifold 46, and the water pump outlet 34, respectively, connecting the air manifold 54 in pneumatic communication thereto.
- the air manifold 54 is connected to the hydraulic plumbing system 36 through valves 70 (preferably check valves) adapted to allow air to flow into the hydraulic plumbing system 36 and to prevent water from flowing from the hydraulic plumbing system 36 into the air manifold 54.
- the air pump 50 may be coupled to the hydraulic plumbing system 36 in any convenient configuration that provides air pressure to the hydraulic plumbing system 36 sufficient to blow any standing water left in the hydraulic plumbing system 36 into the whirlpool bathtub 20 where it can be drained.
- FIG. 3 schematically illustrates the whirlpool water purging system 10 of the present invention in greater detail.
- the air pump 50 is connected to the air manifold 54 through the air delivery conduit 56.
- the air manifold 54 is connected to one or more of the various components of the whirlpool hydraulic plumbing circuit 36 (including the suction fitting(s) 38, the suction conduit 40, the water jet nozzles 44, the water manifold 46, and/or the water manifold conduit 49) through one or more air conduits 58, 60, 62, 64 and 66.
- An electronic controller 75 may be operationally coupled to the air pump 50 to facilitate automatic or manual actuation thereof.
- a sensor 77 may be positioned in the bathtub 20 and adapted to send a signal to the electronic controller when the bathtub 20 is drained or when the water temperature passes a predetermined threshold. Upon receipt of the signal, the electronic controller 75 activates the air pump 50 for a predetermined length of time. Alternately, a sensor 77 may be positioned in whirlpool hydraulic plumbing circuit 36 and adapted to send a signal to the electronic controller 50 in the presence of a predetermined amount of moisture. Upon receipt and for the duration of the signal, the electronic controller 75 actuates the air pump 50 to supply a stream of pressurized air flowing through the whirlpool hydraulic plumbing system 36. The electronic controller 75 may also be operationally connected to a heater 80.
- the heater 80 is preferably positioned so as to be operationally coupled to the air pump 50, and is adapted to provide sufficient heat output to substantially heat the air flowing through the air pump 50 and through the air manifold 54, such that warm, dry air is provided to the whirlpool hydraulic plumbing system 36.
- the heater 80 may be slaved to the air pump 50 such that the heater 80 heats the air flowing through the air pump 50 whenever the air pump 50 is running. Alternately, the heater 80 may be independently controlled.
- the electronic controller 75 may also be operationally coupled to any or all of the check valves 70, such that each of the check valves 70 may be independently operated. Independent operation of the check valves 70 allows the output of the air pump 50 to be concentrated as desired in the whirlpool hydraulic system 36. For example, while the bathtub 20 is filled with water, the check valves 70 connecting the air manifold 54 to the water inlet jets 44 may be opened and the remaining valves 70 may be closed, to concentrate the air flow through the water inlet jets 44. When the bathtub is drained, all of the check valves 70 may be opened to facilitate the rapid purging of water from the whirlpool hydraulic plumbing system 36.
- a series of moisture sensors 77 may be positioned throughout the whirlpool hydraulic plumbing system 36 and operationally coupled to an electronic controller 75, such that the check valves 70 may be opened and closed to concentrate air flow through those portions of the hydraulic plumbing system 36 still containing moisture.
- the check valves 70 may be manipulated to maximize drying efficiency.
- the water purging system 10 of the present invention supplies air pressure to the whirlpool hydraulic plumbing system 36 sufficient to purge remaining standing water left in the whirlpool hydraulic plumbing system 36.
- actuation of the air pump 50 supplies pressurized air that may be used to aerate the water flowing through the water jet nozzles 44.
- actuation of the air pump 50 supplies pressurized air that may be directed through the whirlpool hydraulic plumbing system 36 to force substantially all of the residual water out of the hydraulic plumbing system 36.
- the air pump 50 may further be used to air dry the hydraulic plumbing system 36 by circulating a stream of pressurized air therethrough until the hydraulic plumbing system 36 is substantially dry.
- the effectiveness of the air- drying process may be enhanced by circulating heated air through the whirlpool hydraulic plumbing system 36.
- the water purging system 10 of the present invention may be retrofitted to existing whirlpool hydraulic plumbing systems 36, or may be included therewith as part of a new whirlpool bathtub 20.
